![]() ![]() The main tectonic features are modified from Aurelio et al. The velocity ranges from 4.9 cm/a to 8.5 cm/a ( Yu et al., 2013). The purple lines and circles indicate the GPS velocity and errors, with respect to the Eurasian Plate. Hence, it is possible that several regions are relatively late in their earthquake cycles, which would enhance their susceptibility of being triggered by earthquakes at nearby and regional distances.įigure 1. The tectonic background (a) and focal mechanisms of earthquakes (b) at Philippines archipelago (PA). However, earthquakes with M w > 6.0 were relatively infrequent between 20 at PA. In the past 45 years, the released seismic energy shows certain peaks every 5–10 years. The dynamic stresses from these M w > 6 events are large enough (from 5 kPa to 3532 kPa) to trigger subsequent events, but a lack of seismicity and waveform evidence does not support delayed dynamic triggering among these events, even the shortest time interval is less than 24 hours. However, we cannot rule out the dynamic triggering mechanism, due to increased microseismicity in both positive and negative stress change regions, and an incomplete local catalog, especially right after the first M w 7.0 mainshock. We calculate the static Coulomb stress changes of the first five events, and find that the local seismicity after the 9 M w 7.0 earthquake is mostly associated with positive Coulomb stress changes, including the 1 M w 6.1 event, suggesting a possible triggering relationship. There are six earthquakes ( M w > 6) occurred between 2018/12//09/29 in PA, which provides an excellent opportunity to investigate the triggering relationship among these events. In this difficult time, we are reaching out to ask for your support.Philippine archipelago (PA) has strong background seismicity, but there is no systematic study of earthquake triggering in this region. in a place where public services no longer function.” Currently, 3,000 White Helmets are on the ground in Syria searching for survivors among the rubble and transporting the injured to hospitals in freezing conditions.Īhbap is a cooperation movement that works with value systems based on solidarity, sharing, and belonging through love, based on developing the unifying and transformative accumulation of the Anatolian cultural treasure with the possibilities of contemporary knowledge and technology. White Helmets, also known as the Syria Civil Defense, the White Helmets are a group of humanitarian volunteers who help those in need “regardless of their religion or politics. Red Crescent Society in Turkey, part of The International Federation of Red Cross and Red Crescent Societies (IFRC). If you want to help with a donation, there are many agencies supporting the needs in the region, you can find some examples below: At this time there is no need for international plastic surgeons to be deployed to the area. Thank you to those who have sent offers of support. Humanitarian Team Turkey And Syria Earthquake ![]() Tunc Tiryaki, Chair of our ISAPS Humanitarian Committee, to stay updated on the situation.

Volkan Tayfur and Ali Ertan, from Ankara, and Drs. Our support and gratitude go to the team: Drs. A team of plastic surgeons and four ambulances sent to the area under the leadership of Professor Özay Özkaya, and in coordination with the Turkish Plastic, Reconstructive and Aesthetic Surgery Association (TPRECD), have been working hard to help hundreds of injured and rescue those trapped under collapsed buildings. ![]()
